Con el tiempo, es probable que al menos un 50% de los pacientes con EspAax-nr progresen a EA.2
|
Entre los factores de riesgo para la progresión se incluyen:2
HLA-B27 positivo |
Actividad inflamatoria elevada: - PCR elevada- RM que muestre inflamación de las articulaciones sacroilíacas |
Dolor de nalgas
|
Hábito fumador |
Historia de uveítis |
Sacroileítis de bajo grado
|
La EspAax puede convertirse en una pesadilla para los pacientes, independientemente de que puedas verla en las radiografías convencionales o no.
|
EA: espondilitis anquilosante; EspAax: espondiloartritis axial; EspAax-nr: espondiloartritis axial no radiográfica; HLA: antígeno leucocitario humano (por sus siglas en inglés); PCR: proteína C reactiva; RM: resonancia magnética.
